We look at the division of 90878390 by 47 
We want to divide 90878390 by 47.

Let's proceed to step 1:
If we divide 9 by 47, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 47

Step 2:
If we divide 90 by 47, we get 1 and a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 47 from 90 and we're left with 43.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 47

Going ahead to step 3:
438 divided by 47 is 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 423 away from 438, we end up with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 47

Step 4:
47 goes into 157 3 times with a remainder of 16.
The next digit of our result is 3. 
Result so far: 193.0
Subtracting 141 from 157 leaves us with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 47

Advancing to step 5:
168 divided by 47 is 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 1933.0
Deduct 141 from 168 and we're left with 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 47

Moving on to step 6:
47 can be fit into 273 5 times, resulting in a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 19335.0
The remainder is 38 after subtracting 235 from 273.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 47

Going ahead to step 7:
If we divide 389 by 47, we get 8 and a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 193358.0
If we take 376 away from 389, we end up with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 47

On to step 8:
The number 47 fits into 130 2 times, leaving a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 1933582.0
Subtracting 94 from 130 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
The number 47 fits into 360 7 times, leaving a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 1933582.7
Deduct 329 from 360 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 10:
310 divided by 47 is 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 1933582.76
If we subtract 282 from 310, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
The number 47 fits into 280 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1933582.765
If we subtract 235 from 280, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 12:
If we divide 450 by 47, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 1933582.7659
The remainder is 27 after subtracting 423 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 13:
270 divided by 47 is 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1933582.76595
If we subtract 235 from 270, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
47 can be fit into 350 7 times, resulting in a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 1933582.765957
Subtract 329 from 350 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 15:
47 goes into 210 4 times with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 1933582.7659574
Deduct 188 from 210 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 16:
47 can be fit into 220 4 times, resulting in a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 1933582.76595744
If we take 188 away from 220, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 1933582.76595744, with a leftover of 3.2e-08.
